    Default xmlrpc returns unexpected status

    Hi all I'm trying to use xmlrpc server, because of downloading data from web url to desktop (swing) application. I found XML-RPC and it seems to be great for my purpose. But when I'm trying to connect to xmlrpc, server returns following:
    Java Code:
    org.apache.xmlrpc.client.XmlRpcHttpTransportException: HTTP server returned unexpected status: Not Found
            at org.apache.xmlrpc.client.XmlRpcSunHttpTransport.getInputStream(
            at org.apache.xmlrpc.client.XmlRpcStreamTransport.sendRequest(
            at org.apache.xmlrpc.client.XmlRpcHttpTransport.sendRequest(
            at org.apache.xmlrpc.client.XmlRpcSunHttpTransport.sendRequest(
            at org.apache.xmlrpc.client.XmlRpcClientWorker.execute(
            at org.apache.xmlrpc.client.XmlRpcClient.execute(
            at org.apache.xmlrpc.client.XmlRpcClient.execute(
            at org.apache.xmlrpc.client.XmlRpcClient.execute(
    I followed manual for The XML-RPC Servlet and I wrote these lines into my web.xml
    Java Code:
    <web-app version="2.4"
    			<description>Sets, whether the servlet supports vendor extensions for XML-RPC.</description>
    my servlet looks like this:
    Java Code:
    package services;
    import org.apache.xmlrpc.*;
    import org.apache.xmlrpc.common.*;
    import org.apache.xmlrpc.server.*;
    import org.apache.xmlrpc.webserver.*;
    public class EOTService extends XmlRpcServlet {
    	private boolean isAuthenticated(String pUserName, String pPassword) {
    		return pUserName.equals("username") && pPassword.equals("password");
    	protected XmlRpcHandlerMapping newXmlRpcHandlerMapping() throws XmlRpcException {
    		PropertyHandlerMapping mapping = (PropertyHandlerMapping) super.newXmlRpcHandlerMapping();
    		AbstractReflectiveHandlerMapping.AuthenticationHandler handler =
    			new AbstractReflectiveHandlerMapping.AuthenticationHandler() {
    				public boolean isAuthorized(XmlRpcRequest pRequest) {
    					XmlRpcHttpRequestConfig config = (XmlRpcHttpRequestConfig) pRequest.getConfig();
    					return isAuthenticated(config.getBasicUserName(), config.getBasicPassword());
    		try {
    			mapping.addHandler("Calculator", Class.forName("services.Calculator"));
    		} catch (ClassNotFoundException e) {
    		return mapping;
    (instead of I added handler - I read that this method is fine - but I tried to create too and it's not working)...
    and in the same package I have the class Calculator
    Java Code:
    package services;
    public class Calculator {
    	public int add(int a, int b) {
    		return a + b;
    	public int sub(int a, int b) {
    		return a - b;
    My client is simple, but in accordance with manual
    Java Code:
    try {
                XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
                config.setServerURL(new URL(""));
                XmlRpcClient client = new XmlRpcClient();
                Object[] params = new Object[]{new Integer(33), new Integer(9)};
                Integer result = (Integer)client.execute("Calculator.add", params);
                System.out.println("33 + 9 = " + result);
            } catch ( e) {
                System.out.println("MalformedURLException: " + e.getMessage());
            } catch (org.apache.xmlrpc.XmlRpcException e) {
    When I put http://localhost:8080/eot/service in my browser, it returns exception:
    Java Code:
    HTTP method GET is not supported by this URL
    but it should return this exception, so I think that it works ok.
    Does somebody know, where the problem is? Thank you.

    Look at the servlet URL in your client code...
